.i The present invention generally relates to upholstered furniture andmore particularly to a new and improved edge roll therefor whichprovides simplicity in the assembly thereof and an effective finishedstructure.

As is well known, various forms of edge rolls have been proposed andused in prior types of upholstered furniture. The principal function ofthe edge roll, however, remains the same, i.e. to provide a raisedportion along the exposed edges of the top of the base section ofupholstered furniture which is adapted to positionV and retaincushioning thereon. Although many of these prior edge rolls ,were formedon coil springs having the front or side portion of the uppermostconvolution deformed upwardly, the ultimate manufacturing and assemblyoperation thereof was voftentimes unwieldly and complicated. s

By virtue of the instant invention, the applicant has provided a noveledge roll for upholstered ,furniture which may be simplyand convenientlyassembled prior to the placement thereof on the base 4section of theup-4 holstered unit. The edge roll may be assembled in oney or moreoperational stages onto a hem formedon a wire base member, and thenishedunit readily secured tov coil springsin the base section by theuse of common fastening means, such as well-known hog-rings, for ex`ample. Moreover, the applicants novel edge roll is extremely versatilein that it may be advantageously and a new and novel edge roll forupholstered furniture hav ing multi-layers preassembled onto a hemformed on a wirebase memberwhich is simply affixed to a supporting meansjthereunder through a comm-on clamping device.-

. A further and more general object of the instant inven-f' tion is toprovide a new and novel edge roll for upholstered furniture-which issimple to assemble, whichvis readily placed in position for use andwhich is highly effective during such use. Other. objects and a betterunderstanding of the in stant invention will become more apparent fromthe following description, taken in conjunction with the accompanyingdrawing, wherein: Y

FIG. 1 is a view in vertical section showing the applicants novel-edge'roll in typical use on the base section of an upholstered unit;

` FIG. 2 is a plan view of the-base section for the edge roll-of FIG. l,with the edge roll removed therefrom; j FIG. 3 is an enlarged detailedview in vertical section,

generally corresponding to the view of FIG. 1, showing theapplicantsnovel invention; and,

" FIG. 4 is an'enlarged fragmentary view in vertical section showing theedge roll forming theinstant inven tion at the time of'preassembly.

A` I or the; purpose of promoting an understanding ofthe principlesofthe invention, reference willznow be made,`

United States Patent O to the embodiments illustrated in the drawing andspecific language will be used to describe the same. It willnevertheless be understood that no limitation of the scope of theinvention is thereby intended, such alterations and furthermodifications in the illustrated device, and such fur` ther applicationsof the principles of the invention, as illustrated therein beingcontemplated as would normally occur to one skilled in the art to whichthe inventionv the top surfaces of the base rails by conventional means,

such as by ta'cking, for example.

Extending upwardly from the base Wires 16 are conventional coil springsl'wliich, in the preferred embodiment of the invention, increase indiameter in an upward direction. 'The coil springs 18 disposed along theouter edges of the base section"10, i.e. adjacent the front or adjacentthe sides where there is nof'upholstered arm, each have the forward and/or side portions, respectively, of the uppermostv convolution thereofdeformed upwardfv ly,all as well-known in the art. Theuppermost con'-volutions of each'of'the coil springs '1,8 are `secured to a tangentialedge wire' 19 through the useof clamping devices 20, thereby forming anupper framework for the coil springs 18 of the spring assembly.lincreased stability for the overall spring assembly is further attainedby the use of wires 21 which are deformed at 21a beneath and around anedge of the top of each of the coil springs 18, which deformed portionsare hooked together by small sections of wire 22.

It should be understood that the aforedescribed struc-V ture isconventional in the'art and the discussion thereof herein is merely abasis for an understanding of the'applicants novel invention which,inthe preferred embodif` ment, is used therewith, and s peciliedetailedrstructure has been omitted for reasons of clarity.

Referring now particularly to FIGS. 1, 3, and4, the applicants new andnoveledge roll 25 comprises, when assembled, multi-layers including,from bottom to top in' the preferred embodiment and atthe line ofstitching,l a hem 26 encircling a Vpaper-covered wire member"v 27;l aninsulator layer 28, typically silatex materiaLfor example, positioned onthe top of the spring assembly of the upholstered unit, silatex being ahemp impregnated with latex rubber; a layer of padding material 29,Vsuch asA cotton, lfor example; and, a decorative fabric 30 and a denimmaterial 31 arranged so that the decorative fabric 30 overlies the denimmaterial 31 in typical u use,`- with all of the precedingcornponentsstitched together through the hem 26 to form an integral preassembledunit. The aforementioned components of the appl-icantsv newandimprovededge roll are secured and/or positioned with reference tothe springassembly in the base section 10 of the upholstered unit in a detailedfashion which is to be discussed .more fully herebelow.

As already mentioned, the edge roll 25 vforming the instant -inventionvmay be `simply and effectively preas# sembl'ed in one or moremanufacturing operations, as desired. ANoting particularly FIG. v4 whichillustrates the relationship of the various components form-ing the edgeroll 25 prior to the preassembly thereof, the hemY 26 is looped aboutthe paper-covered wire member 27 so' that each side extending.'therefrom 4is substantially the Stuneize..` ,In lpractice,l such' aArelationship can 'be Patented Dec, 18,

. l o achieved by feeding the hem material, in the form of a tape,together with the paper-covered wire 27 through a guide or footing (notshown) on a standard sewing machine.V v

v Disposed above the hem 26' is the insulator layer VK28 which is ofsuch length so that when positioned onethe springv assembly, the freeends thereof may each be turned under the edge wire 19 and stitched backon itself. The padding material 29 is thendisposedv over the insulatorlayer 28, which padding layer 29 should be of sufiicient length so thateach free end thereof hangs down-V wardly partly over the sides of thespring assembly,` (see FIG. 1). j,

The edge roll is then completed by the decorative fabric, and lthe denimmaterial 31 which, when joined,V

are laid over the padding layer 29. The denim material illv isV of alength which permits the tacking thereof-onto the back surface of therear base rail 12, while the decorative fabric 30 is preferably of suchlengthto permit it -to be drawn forwardly, when in use, over the paddingmaterial 29, downwardly infront ofthe base section 1t), and thenr tackedonto the under surface of the front base rail 1f1. The aforementionedlayers forming the applicants new andl novel` edge roll are thenstitched together, at a l-ine defining a throat, to make an integralunit which may be readily placed on the base section 10 of theupholsteredunit during the manufacturing operation.

v In typical/use, the preassembled edge roll 2S is laid over the springassembly in the base section 10 andV fastening means, such as thewell-known hog-rings 35, are used 'to secure yit to wires forming theuppermost convolutionof the coil springs l18. ,As should be apparentfrom FIG. 3, the hog-rings encircle the paper-covered wire 27 and piercethe hemV 26 extending therearound. The opposite ends and sides of theinsulator layer 28 are thenY drawnV in` a reverse manner over the edgewire 19 and CIK stapled/together thereon. The denim material 31 is theni drawn tightly back over the padding material 29 and attached to theback surface of the rear base rail 12, while the decorativefabric 30 isdrawn forwardly over the padding material 29 on the deformed portions ofthe uppermost convolutious of the coil springs 18 and downwardly forattachment to theunder surface ofthe front base rail'11. Y

It should be apparent thatl no stitching is visible with the use of thisnovelY edge Yroll inasmuch as the decorative fabric 30 coversthestitched line when fthe edge roll is secured to the spring assemblyduring use. Moreover, it should be .understood that securing thepreassembled edge roll onto the spring assembly in the base section 10of the upholstered unit may be achieved in alternate effective ways,including the stapling of the back edge of the insulator layer 28 ontothe edge wire 19 iirstfol lowed by hog-ringing the paper-covered wire 27onto a wire formingthe uppermost convolution of each of 'the coilsprings 18, and then stapl-ing the forward edge of the insulator layer28 onto the edge lwire V19, with the decorative fabric 30 and the denimmaterial 31 thereafter being secured Vfor use as discussed hereabove.

Insofar as the preassembly of the edge roll 25 is concerned, it shouldbe noted that this operation can be in a single step, as discussedhereabove, or in two or more steps. For example, in a two-step system ofassembly, the decorative fabric 30 and the denim material 31 'may firstbe stitched together, and the complete unit then' integratedV by thestitching operation discussed above.

Moreover, it may also bedesirable to omitrthe paddingV material 29 fromthe stitching operation, with this being placed in positionV later,where desired, without sewing therethrough. In the latter instance, thestitching for preassembly would combine the decorative fabric 30 and thedenim material I31, which could already be stitched together, theinsulator layer 28, and of course, the hem 26 formed on thepaper-covered wiref27.

. From the preceding, -it should be apparent tha-t the applicanthasrprovided a novel edge roll for use on upholstered furniture. Theedge'roll is susceptible to simple preassembly techniques, and may bethen effectively positioned on the desired upholstered unit to therebysimplify the overall manufacturing operation. The edge roll may beunited in one or more preassembly operations withr equal effectiveness,while the ultimate use' thereof is without any visible stitching.

lt should be apparent that the edge roll described herein is susceptiblerto various` changes withinthe spirit of the invention. For example, andas indicated hereabove, the padding layer 29 may be united with the edgeroll during Ithe preassembly operation or may bek inserted when the edgeroll is secured to the spring assembly in the base unit 10 of theupholstered article of furniture. Moreover, the

'hem 26 formed on the paper-covered wire 27 may extend towardv the-front'of the upholstered furniture rather than the rear, as indicatedin the fgures. Although not disclosed in the drawing, it should befurther understood that a wire, generally corresponding in 4function tothe paper-covered wire 27,- may be interspersed with the insulatorlayer, i.e., as by weaving, for example, for'equally effective practiceof the invention. Furthermore, it should be understood that the overallassembly of the edge roll onto the spring section is the same for thesides as for that aforedescribed. Thus, the above description should beconsidered illustrative and not as limiting the scope of the followingclaims'.
